Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment technology, specifically an adjustable ultrasound probe-guided puncture stent. Background Technology

[0002] An ultrasound-guided puncture stent, commonly known as an ultrasound probe puncture frame, puncture guide, or puncture guide, is an important medical device. It is an auxiliary device mounted on an ultrasound probe, allowing doctors to precisely guide the puncture needle to the target location on the body under real-time ultrasound guidance, achieving accurate puncture. It is mainly used in medical procedures such as cytological biopsies, histological biopsies, cyst aspiration, and treatment.

[0003] However, the needle fixation components of existing ultrasound probe-guided puncture stents are mostly located in a fixed position on the stent, which can only be adjusted within a fixed range. It is difficult to adjust the position of the needle fixation components according to the user's usage habits or the special situation faced during puncture, which makes the device have certain limitations in use. Therefore, an adjustable ultrasound probe-guided puncture stent is proposed to address the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1-3 As shown, an adjustable ultrasound probe-guided puncture support 100 includes a fixation frame assembly 10 for fixing an ultrasound probe (not shown) and a puncture adjustment assembly 20.

[0025] The fixed frame assembly 10 includes a frame 1 for mounting the handle of the ultrasound probe, a fixed claw 21 and a movable probe claw 3 disposed opposite each other within the frame 1, and an adjusting screw 2. The frame 1 has threaded holes (not labeled in the figure) adjacent to the movable probe claw 3. A bearing 31 is provided on the back of the movable probe claw 3. One end of the adjusting screw 2 is connected to the bearing 31, and the other end passes through the threaded hole and is disposed outside the frame 1, allowing adjustment of the distance between the fixed claw 21 and the movable probe claw 3 to clamp the handle of the ultrasound probe. Figure 2 and Figure 3 By rotating the adjusting screw 2, the moving probe claw 3 is moved to one side of the fixed claw 21, so as to adjust the distance between the fixed claw 21 and the moving probe claw 3, thereby cooperating with the fixed claw 21 to clamp the handle of the ultrasonic probe.

[0026] The puncture adjustment assembly 20 includes a slide rail 4 disposed on the outer side of the frame 1, a slider 5 slidably disposed within the slide rail 4, an adjustment mounting plate 6 rotatably connected to the free end of the slider 5, and a needle holder 8 fixed to the adjustment mounting plate 6; wherein, the position and angle of the puncture needle fixed on the needle holder 8 are adjusted by the rotation of the adjustment mounting plate 6 at the free end of the slider 5 and the sliding of the slider 5 within the slide rail 4.

[0027] Specifically, in use, the frame 1 is first placed on the outside of the handle of the ultrasound probe. The moving probe claw 3 is moved by rotating the adjusting screw 2 and works with the fixing claw 21 to clamp the handle of the ultrasound probe. Then, the position of the needle holder 8 is adjusted by sliding the slider 5 in the slide rail 4. The angle of the needle holder 8 is adjusted by rotating the adjusting mounting plate 6. Thus, the position and angle of the puncture needle are adjusted, achieving the purpose of multi-angle and multi-position adjustment according to the puncture situation and the user's usage habits.

[0028] Preferably, the fixing claw 21 is fixed to the inner side of the frame 1.

[0029] Furthermore, the retaining surface of the fixed claw 21 is provided with a rubber pad 200, and the retaining surface of the moving probe claw 3 is provided with a rubber pad 200.

[0030] When the rubber pad 200 is held in place by the handle of the irregularly shaped ultrasonic probe, the deformation of the rubber pad 200 allows the fixed claw 21 and the movable probe claw 3 to fit snugly against the outside of the ultrasonic probe handle, thus holding the probe handle securely without damaging it.

[0031] Preferably, the slider 5 is interference-fitted with the slide rail 4, thereby achieving stable sliding of the slider 5 within the slide rail 4.

[0032] Preferably, the frame 1 is square and consists of four borders; at least two adjacent borders are provided with connected slide rails 4 on their outer sides, thereby enabling adjustment in more positions.

[0033] Preferably, at least one end of the slide rail 4 has an open structure; a limiting part 22 is detachably provided at the opening to prevent the slider 5 from dislodging from the slide rail 4.

[0034] Preferably, the slide rail 4 has a T-shaped cross-section.

[0035] Preferably, the adjusting mounting plate 6 and the free end of the slider 5 are rotatably connected via a rotating shaft 7 or a ball joint to achieve rotation at more angles.

[0036] Specifically, in this embodiment, the adjusting mounting plate 6 is L-shaped; the end of the first arm of the L-shape is rotatably connected to the free end of the slider 5, and the end of the second arm of the L-shape is connected to the needle tube fixing frame 8.

[0037] Preferably, the needle holder 8 is rotatably fixed to the adjusting mounting plate 6 to achieve more angle adjustments.
